本発明によれば、搬送台車が搬送路上を昇降及びカーブ
する場合にも十分な推力が得られるリニア誘導モータ式
搬送装置が得られる。[Effects of the Invention] According to the present invention, a linear induction motor type conveyance device is obtained that can obtain sufficient thrust even when the conveyance vehicle moves up and down and curves on the conveyance path.
特に、一方のリニア誘導モータの１次側に対して２次側
導体が凹面を形成する場合に、他のリニア誘導モータの
２次側導体は１次側に対して凸面を形成するので、推力
が極端に減少することが防止でき、良好な搬送が保障さ
れる。In particular, when the secondary conductor of one linear induction motor forms a concave surface with respect to the primary side, the secondary conductor of the other linear induction motor forms a convex surface with respect to the primary side, so the thrust can be prevented from decreasing excessively, and good conveyance can be ensured.
